I removed the shift kit the builder installed and installed one from ck performance and took pressure readings yesterday.. are these safe pressures?

hey guys
I went ahead and drove it a mile down the road.. it shifts at about 150psi. Shifts a little later than i like but i can live with it..1-2 is firm and will bark the tires when you are past 3/4 throttle (even then the shift is not bone jarring).... 2-3 is not as firm but noticable (which i like since it is a cruiser)... 3-4 is a nice bump however this shift comes in a little too soon.. i spoke with chris about this he said i may have to install a stiffer 3-4 shift spring. I was just worried about the pressures cause the orginal kit had 250psi at full tv.. now i am down to around 210- 215

I like 250 as a min at max TV. I would not feel safe that the trans would live with those pressures.

That does look a little low. Chris should be able to help.

Yes they look a bit low. The CK kit should get you 250 psi, maybe a bit more with a good pump.
